Abstract
Abstract We analyze the heat transfer phenomena in a narrow confinement filled with Couple Stress fluid (taking into account molecule size effect) driven by the simultaneous influence of pressure gradient, electrical potential and the peristaltic pumping in the presence of magnetic field. The effects of Joule heating, permeability of the porous medium and dissipation of energy are taken into account. Entropy generation in terms of Bejan profile and the Nusselt number under different parameters are investigated. The analytical method has been invoked to find the closed from solution of the thermo-fluidic governing equations. The study reveals that the zeta potential has significant importance in controlling velocity and thermal response in the system. The Joule heating effect and Brinkman number both are equally responsible for enhancement of thermal irreversibility measured in terms of Bejan number profile. Thus the study bears potential applications in industrial and biomedical technology for developing microfluidic devices.
